  • Quality of service tier thermal control
    Patent number: 11809256
    Abstract: Embodiments are presented herein of, inter alia, systems, devices, and associated methods for allocating and distributing power management budgets for classes of tasks being executed by a computer system, based on thermal feedback loops. Specifically, multiple quality-of-service (QoS) tiers may be defined, and each QoS tier may be allocated power based on a different set of thermal feedback loops. QoS tiers including tasks that are invisible to the user may be mitigated more aggressively than QoS tiers including tasks that are visibly supporting user operations.

  • Coherent power management system for managing clients of varying power usage adaptability
    Patent number: 11513576
    Abstract: Systems and methods are disclosed for allocating and distributing power management budgets for subsystems (e.g., power usage clients) of a computer system. A power budget allocation subsystem may include a plurality of feedback branches having different associated time constants. Power usage clients with slower power response times may be provided power budgets based on a feedback branch having an associated longer time constant, while power usage clients with faster power response times may be provided with power budgets based on a feedback branch having an associated shorter time constant. The power budgets may be determined in the feedback branches based on power budgeting policies weighting the power budget of each subsystem relative to total power mitigation.
